I'm a relatively new cat owner and have figured out that Alan (Tuxedo aged about 7) doesn't like:
All wet food types with fish
Tuna (!)
Tinned mackerel
So basically hates fish!
Any human food fresh cooked chicken etc.
What he does love is:
Sheba chicken/turkey flakes in GRAVY (oh and cheddar cheese). He likes Lidl complete cat food too (chicken only).
Did my shop yesterday and bought a new supply of Sheba fresh and fine, but when I went to give Alan his tea it kind of plopped out instead of me having to force it. Chopped it up a bit and Alan took one lick and turned away in disgust!
I'd bought Sheba in jelly not the beloved gravy.
I can see why though...
The packets are nearly identical! So annoying!
